Issue installing extension: stalls on "Update is already in progress"

[vedanet]

Hello,

Preconditions: Magento 2.3.0 PHP 7.2.xx

Summary of the Issue

The problem occurs with all extensions.

I am trying to install stripeofficial/stripe-payments on Magento 2.3.0 using extension manager and when it gets to the Component Install phase it stalls after: ./composer.json has been updated and continues to print Update is already in progress

[2019-03-25 07:45:04 UTC] Job "setup:cache:disable []" has been successfully completed
[2019-03-25 07:46:03 UTC] Job "update {"components":[{"name":"stripeofficial/stripe-payments","version":"2.0.9"}]}" has been started
[2019-03-25 07:46:03 UTC] Starting composer update...

I have looked around at several solutions and have tried the following:

1. Checked permissions for the /var files
2. Removed the .update_in_progress.flag and the .maintenance.flag

Actual Result

It doesn't get installed

When I remove the two files mentioned above, I get:
Success Your store is no longer in maintenance mode. You installed: stripeofficial/stripe-payments

But when I go back into the admin panel stripe-payments isn't on the sidebar, and if I check the install wizard it has not been installed.

Any guidance on the next steps to take to get this resolved would be greatly appreciated.

Your solution is not correct

When I remove the file

.update_in_progress.flag

I get:
Success Your store is no longer in maintenance mode. You installed: stripeofficial/stripe-payments.

But when I go back into the admin panel stripe-payments isn't on the sidebar, and if I check the install wizard it has not been installed.

How should I solve this problem and install extensions?
